What should I do with an account left idle for months?

Pick it up with one piece of how the place looks today, with hours and a way to book, and skip the apology for the gap. Deleting the account does not fit if it still holds the name and the reviews: archive the old material and continue. Check that access is still in your name and that the Google listing points at that profile. A carousel apologises, and the next piece still shows the menu that no longer exists. The restart is one current piece, an up-to-date bio, and the old material archived, on the same account.
